SHIKI-HOLDER.

Specification of Letters Patent.

Application filed January 20, 1919. Serial No. 272,081.

, the holding of shims against the upper half of a bearing, such as a connecting rod, `while the lower half is removed for repairs, or

for changing the amount or number of shims' between the halves of a crank pin bearing.

The object of my invention is to permit vthe removal of the cap which secures the 'connecting rod to the crank shaft without the inconvenience of holding the shims by hand, or removing same until the cap is restored to place, which operation, on account of the position of the parts, is quite difficult.

A further object is to remove the danger of dropping the shims and changing the number and arrangement of same on the bolts.

Referring to the drawing. Figure l, is a front elevation of the lower end of a connecting rod showing the manner vof applying my device. Fi 2 is a side elevation of Fig. l. Fig. 3 1s a plan of the device, and Fig. 4 is an elevation of same. Fig. 5 shows a modified form of lnydevice.

Referring in detail to the drawing. C1 is the usual form of connectingrod found on .internal combustion engines. C2 is the upper half of the crank pin bearing of which C3 is the cap, the two parts of the bearing Y being held to ther vby means of the bolts C4, from whicIi the nuts have been removed for the purpose of illustrating the action of my device. The bolts C4 pass `through the lugs C and the shims S1 and S2, said shims having the shape of a cross section of the crank pin bearing at the point of union of the halves. C5 is the under side of the' con` necting rod bearing, and C is the upperl side of the cap C3. Bearing C2 and cap C3 are 'supported by the shims S1 and S2. H1 is the handle-of my device, which is a wire bent into the form of a U with its open ends converging, each one forminga reverse curve near its point, the cui-ves bemg opposite and facing each other so that the two curves H2 constitute recesses'whch form a pocket. which is the point at which my device secures itself to the bolts C4, While the serve to help in causing the mouth M1 of m devlce to pass around the bolt. C. Curve 5 acts as a shoulder to improve the clamplng effect of the device, the sides Hl being held together to produce a spring effect on the two free ends of the device. The sharpened points H4 assist in inserting the ends o f the device between the lower shim Sl and the face CF.

The Figs. l and 2 illustrate the means of applying the device in order to prevent the shims from falling moved. It will be seen that the shims S2 which are not so held are resting on the face C6 and will come oif with the cap C3.

The operation of my device is as follows: When desiring to remove the cap C3 of the connecting rod C1 for any purpose whatsoever, it is only necessary to loosen the nuts of the bolts C* suiiiciently to allow the points H4 of :myV device to be inserted between the lowermost shim S1 and the face C? of the cap C3, Aand by pushing same toward the center of the crank pin until-the'bolt C* occupiesthe space between the curves H2. The cap C3 may now be completely removed While the shims S1 retain lthe position shown in Fig. 1. 1

As illustrated in Fig;

e round wire, which has a number of advantages such as thin tipswhich assist in insertin same between shims and flat finger grips. `1 represents the arm members of my device constructed of fiat spring wire. F2' is the bolt clasping recess. F3 are the Haring tips for assistance in nding the bolt.

While I have thus described my invention, it is not my intention to limitk myself to this precise form, but intend that it shall cover all forms and modifications that fall fairly within the appended claims.

What I claim as new and desire to protect by Letters Patent of the United States is 1. A shim holder consisting of a U shaped member constructed of fiat wire whose free ends are twisted into the same plane and whose adjacent sides touch each other and have a recess formed between them an'd hav# ing the extreme tip formed into diverging curves in a manner to assist in finding a' bolt,

said extreme ends having chisel sha ed tips having the closed or handle portion of said Patented Feb.15, 1921.

oli when cap C3 is reno p shim holder bent downwardly at an angle to v 2. A shim vholding device consisting of a 4U shaped 'member having opposed recesses formed in the parallel members thereof in the inner sides ,thereof and having the extreme tip of said open ends in wedge form.

3. A shim holding device consisting of a 10 U shaped 'member having opposed recessesformed in the parallel members thereof inthe I inner sides thereof and'l near the open ends and having the closed end of said U shaped l member bent downward from the horizontal plane in which lie the' two open ends of said U shaped member GE ORGE H.
